, Application filed September 23, 1921. Serial No. 502,623;

Be it known thatWG,-GUSTAVE D/I. GOLD- sMrTH and CARL P. BARTELS, citizens of the United States, residing atI-lamilton, Butler '5; county, Ohio, have invented certain new and useful Improvements in Pressure Systems for Safe or Vault Doors and the likepof whichthefollowing is a specificatio'n.

This invention relates to pressure systems for safe or vault doorsandt-helike, and in particular, relates to a pressure system adapted to be internally adjusted intopper able or inoperable condition for closing or for preventing the closing of the safe or vault door on which the system is mounted. Our invention further relates to a power transmission device adapted to be associated with a pressure system so as to be operable to establish or to disable a driving connection between a driving element, such as the pilot wheel, and a driven element, such as the worm shaft, of the pressure mechanism.

. This invention is broadly similar to the invention covered in our application filed on.

{September 23,1921, Serial N 0.502,? 23 relatmg to improvements in pressure systems for safe or vault doors and the like.

The pressure system of a vault or safe is a mechanism carried on the outside of the vault orsafe door whereby the vault door may be forced into absolutely closed 'posi tion and thus enable the locking bolt-s'to' be operated to. lock the vault. The mechanism is adapted to be driven by rotating a hand wheel, commonly called the pilot wheel, this wheel being customarily in permanent driving engagement with a worm shaft which connects through a series of gearing with a plurality of rotatable pressure bars carrying into absolutely closed position in the door frame or jamb. Any one may operate-such a pressure system 'by' merely turning the pilot wheel. Thus, no protection is given to a person within the'open vault from, being Y locked inside" by an unauthorized person,

such as a daylight bank robber; OIIQ'Of the objects of our invention is to provide a pres sure system incorporating means, preferfi-bly concealed, and operable in a secret til cams adapted to engage with bars or blocks manner, whereby the system may be readily and easily adjusted into operative or into 1noperativecondition, thereby enabling an au-' thorized. person before entering the vault to i and enabling such person torestore the 7 place the device into inoperative condition devioe into operative condition'when he de sires to d so. A'further-object of our in-f vention'is to provide a device ofthe'eharacter describedwhich is secret and is atlapt ed'to be controlled-by secret. means, such; as

a combination lock or a key loclg oi" by tlie secret movement' of a movable member. A,"

further object, includes ftheimounting er 'a device of such character on the pressure system so that its p resence will not be readily apparent to. a casual observer. Other objects' will be in part obvious and in part pointed out hereinafter;

7 One f the advantages obtained byour invention is that, the pressure' system nlay-be disabled-so that an unauthorizedrperson, ig-

norant of the presence of the anti-locking device, or not supplied withthe proper key or combinationnecessary for its operation, may not "work the system to close the door of the vault. By'this means an unauthorized person, such as a bankrobb'eif, is} prevented from locking employes "of the bank inside of the vault after" an attempted burglaryl Yin authorized person is'able to set the device so that the system may be operated to close the vault door or may adjust the device so 1 that the system inoperative and will prevent the olosingiof the vault door except a personhaving knowledge of the existence of the device and ,of its operationQ The op eration'; of the anti-locking'ldevicefbeing con trolled by a lock mechanism, the adjustment ofthe pressure'systein from inoperativeto operative condition may not; be accom-- plishcd by an unauthorized person,"and foils the efforts of sucl1 ,person' 'to'-,close the vault'door whereon'the is" m unte Other f advantages *wi l1= become apparent hereinafter. i

lnlla'ccordance with tour invention, of mounting the pilotwheel of thepre'ssure j system j in, permanent driving engagement withftheworm shaftjthereof, ashasheretof t" I fore. been customary, we mount the pilot;

ivvheel for free revplution on the worm shaiti i We provide a-lpow'e'r transmission device controlling f mechanism therefor .uq

and, a V v whereby a driving enga ement betwe e he pilot wheel and the worm shaft may be 65- tablished or disabled, thus placing the pres sure system in operative or inoperative condltion. Such a power transmlssion device may comprise a locking element, such as a be controlled by means of a lock mechanism of the combination or key type carried on the pilot wheel,- the bolt of the lock being connected with a movable plate provided with stops which coact with and guide the movement of a movable member or collar carrying the locking key or dog. The stops and .the oollar carrying the locking dog are so associated with each other that when the stops are moved into one position in response tov movement of thelocking bolt, such as into unlocked position, the stops hold the dogout of a recess of the wormshaft, and when the stops are in another position, as

when the bolt of the locking position is in extended or lockngpositio nwe dog may enter,

arecess in the worm shaft. Preferably means are supplied to continually urge the key or dog to move toward the worm shaft and into recess therein so that such movement may be accomplished whenever the movementof the stops permit. In place of a combination or key lock we may substitute a knob movable axially against the action of a spring into engagement with a rotatable mtembercomprising an eccentric so that the eccentric may then be rotated by the turning ofthis knob. The eccentric co-operates with afbolt or plate carrying the stops which govern the movements of the locking dog or key into or out of the. recess in the worm 7 shaft. By manipulating the knob'into engagement with the eccentric and then turning the knob the dog may be directed to enter or to leave the recess ofthe worm shaft and accordingly a driving connection may be established or disabled between the worm shaft and the pilot wheel. Thus, by the proper manipulation of a lock mechanism or knob. above described, the pressure system may be placed into operative or into inoperative position andv the pressure system may not be converted from inoperative to operative condition except by moving the bolts of the control mechanism into unlocked or withdrawn position, and such movement of these bolts may not be accomplished except by means of a proper key for the key lock, or the working of the "proper combination of the combination lock,

'- or the proper preliminary adjustment of the knob of the control meanslast described.

7 In order that a clearer understanding of car mvent on nay be had atte tion here illustrated one poss by directed to the accompanying drawings illustrating certain embodiments of our invent on. In the drawings, Fig. 1 1s a front plan view, somewhat diagrammatical, of our invention associated 'with a pressure sys.

the pilot wheel without invention thereon,

showing the pilot wheel unlocked from the worm shaft, certain parts. being broken away for the sake .of clearness; Fig. 4 is a view'of certain of the parts shown in Fig. 3 and shows the pilot wheel and worm shaft locked together; F ig. 5 is a .fragmentaryv sectional view taken on the line 55 of Fig. 8; Fig. 6 is a view similar to Fig. 3 but illcludes a key lock control; Fig. 7 Y is similar to Fig. 2 except that it shows the lock illustratedin F ig.',6; Fig. 8 is. similar to- Figs. 3 and 6 but shows another form of control. for the power transmission mechanism; Fig. 9 is a sectional view similar to that of Figs. 2 and 7 but shows the control mech-. anism illustrated in Fig. 8, the view being taken on line 99 of Fig. 8; Fig. lO is an enlarged view of a detail of the control. mechanism illustrated in Figs. Sand 9-; and Fig. 11 is a sectional view of a detail taken on the line 11-l1 .of Fig. 10. Similar reference characters designate similarv parts ed for" rotation in bearings 5 on the outside of door 2, and having at their outer ends cams 6 adapted toengage with bars or blocks 7 attached to the door frame 1. A series of gearing (not shown) permanently connects pressure bars l; to a worm shaft 8 which is mounted for rotation on the door 2. Power is transmitted toll-11G pressure mechanism by. means of a hand wheel 9, commonly known the pilot wheel. whicliis fitted. with a phi: ral-ity of handles 10. llllhee-l 9 is mounted for free rotation on. shaft 8, operable means being supplied whereby the wheel 9.- maybe locked to or be unlocked from shaft 8 to es ablish or to disable a driving connectinn between said wheel and, shaft and thereby place the pressure system in operative or in inoperative condition. Obviously many various ways and means may be. f employed w ich are qperable to. establish orto disable a driving connection between the pilotzwheel and the worm, shaf 1 construction for es 1 3 2: .eel, an

o l; for dis I In the drawings is led "a locking keyior dog 14 adapted to be movedandllocked into .or-tobe moved out of and to become unlockedl from suitable key-ways" the portion20 on the pilot wheel. The part 20 may be suitably secured to therear of-the wormshaft, and several modifications of controlling means for controlling the operation of said-power transmission means.

Referring-to the drawings, aplate or 061- "lar 11 is slidably mounted on the back of.

the pilot wheel 9 in a slide or guide 12 machined between two lugs113+-'13, and carries or recesses 15 'formedtherefor' in the worm shaft 8. Collarll contains an elliptical perforation l6'through which worm shaft '8 extends, collar 11 being movable'radia'lly in respect thereto. Collar :11 and :key 14 are continually urged to move so as tobring the key 14 into locking engagement within a re- 9915 by means of a coil spring 17 coiled about a guide pin 18. mounted-on a part on pilot wheel 9, pine-l8 being adapted to be loosely received in a suitable recess 19in one end of collar 11, and the spring 17: being compressed between this end of collar 11 and pilot wheel 9 by means of screws 20.

To govern the movement of the collar 11, and, accordingly, the movement of the dog or'key 14 into or'out of a recess 15, we provide a movable shifter iplate '21 underlying plate 11, and slidably mounted in the guide- 12 provided between the lugs 13. Shifter plate 21 is slotted as at 21,"with worm shaft 8 extending through theslot 21', shifter 1 plate 21 being movable radially in respect to this shaft: 'On'shifter plate 21 we provide stops or pins 22, which stopsextend through elliptical perforations 23 in'platee 11. Slots 23'and the pins 22 are so-larranged that movement of the pins 22- causes the movement of the'locking dog 14jinto orgout of arecess 15 in the worm shaft. We provide a mechanism for controlling the movement of the shifter plate 21 together with'lpins 22 thereon in respect to shaft 8. n

In one embodiment of ours-invention, such 9 as is disclosed in'Figs. 1, 2pa'ndu3vof the drawing-s, we, provide a combination lock 23 of a well-known type and connect the outer I end of its bolt 25 with shifter plate-21, as at V 26, so that'by o-peratinggthe bolt 25 into locked or into unlocked position the shifter 7 plate, together with its pins 22, will be or into operativecondition. 'Asshowm-the.

moved relatively to theshaft 8, and thedog 14 will be accordingly unlocked from or be' locked within a recess15 in shaftS, thus adustmg the pressure-system into lnoperati-ve 1 cordingly. disablethe operative connection between the. pilot wheel 9.1 and the worm 1 shaft 8, :andl thusadjust the pressure'sys 5 tem into inoperative condition; The 'pres-. sure systemmay not be restoredinto opera--- rtiv'e condition except by withdrawingthe f bolt bar25 into unlocked position, and this may not be accomplished without properly working the combination of the combination T lock 23. Thus, an authorized person is able to.

prevent the-pressure system from being op-' erated andithe vault door-from being 'closedf. I

by an unauthorized person-P Preferablyfthei combination lock 'ismounted so that its dials and'knob are on theouter or-exposedf facev of the pilot wheel; 1

I Instead of the combination"lock aboveide-" scribed we may substitute ak'eyjlock mechanism for controlling the op'erationof the power transmission 'i'devi'ce; When a key lock mechanism is employedfwe preferably mount the same'in the manner illustrated-in" Figs. 6 and 7' of the drawings, withthe lock mechanism :30 mounted within the' pilot wheel 9 and the key tube 31 with the keyhole 31, exposed on the imderneath orcon cealed faceof'the pilot wheel 9. The "control 'of the power transmission mechanism is similar to the control; accomplished by means of the combination lock 23, thebolt bar 25 of the key lock 30 being similarly connected to the shifter plate 21, as at 26,

by means of screworbolt 32. Thei'nove- V ment of thebolt bars 25a-of'boththe com'.

bination lock 23*and key lock30 control similar parts in a similar mannenu How-.

ever, when the key lock is present-the bolt bar 25 may onlybemoved'in resp'onserto the use of the proper key and, in addition, I

the presence .of the. anti-lockingdeviceis' concealed. 7 I a V i 5 As another means for controlling the movement ofr shifterplatei2l-to cause the locking dog 14 to be moved into or out of a recess 15 we may extend shifter plate'21 outwardly as at-4O, and provide in said ex tension an ellipticalperforation 41Eadapted to receive aca'mor'eccentric 42 carried on the end of a pin 43"rotatably mounted on the :pilot wheel9 as at 44. Vi e: provide a knob 45 held {l1}. position on'the vpilotwheel 9 by meansof-split flanges 46 so as to be rotatable ion the wheel, saidknob being pro;

vided with a sleeve-like extension 47 adapt.-

ed to loosely encircle-the outer end of pin 43. .We mount lm0b'45 axially with respect to pin 43 and provide a coil-sp-ring48 seated between the v sleeve 47 and the periphery 1 of the; pin: 43 a-nd compressed between i an annularshoulder49 provided on the insideof the sle'eve'47 and an annular shoulder49 provided on the pin 43 to maintain the knob 45 inoutward position in respect topin 43.

On the outer-end. of ,pi-n43, we provide a slot adapted to receive,--a;pin carried enter into said slot 50 when knob 4C5 has been pressed inwardly and is adapted to be 4-2, but when the knob l5 has been pressedout of engagement with said slot when the sa-idi :knob 4:5 in'normal position or disposed outwardly of said 4L3.v Thus, it

will be apparent that when the lmob -15 is V in its normal position inrespect to pin 1-3;

it: be rotated freely without affecting the rotation of the-pm 43: or the eccentric inwardly of the pin '43 so that the pin 5i on the 'knob is engaged in the recess of g the pin 43, the tnri'iing of the knob 45' will efiect the turning of the pin 43 and the eccentric 4:2, and will correspondingly movethe shifter plate- 21 radially of the worm wheel shaft 8. T has, normally the knob l5 may be rotated freely without. affecting the;

conditionof the driving connection between the pilot wheel and the worm shaft, but

ment with the pin l3. and'when in this position may be turned to establish or to disable a driving connection. between the pilot wheel 9 and the worm shaft 8 and accordingly adjustthe pressure system into opera-- tive or into inoperative condition..- Preferably welnOLIIllE the knob 45" on. the underneath or concealed sideof thepilot wheel 9 so that the presence of the. anti-locking device and of the knob 'i-a' nipu lating the same are concealed and will not'ibe apparent to unauthorized person.

if desired the entire" locking and controlling mechanisms may be concealed and held in position. by means of a substant-ial confer p ateofi secured to" the back of the pilot wheel 9'. An ornamental nut 53 may also be secured to the outer end} of worm shaft 8 From the foregoing description the operation of the power transmission device and the control mechanism therefor will be: readily understood; 7 As many changescan be made in the-- above construction and many" apparently widely different; embodiments: of this invention could be made without departing-from the scope thereof, it is intended that all i natter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and'not in alimiting' sense.
